I think I would just add a taller fence or chicken wire to the top,on your side of course. At some point big dog isnt going to be able to sail over the fence.

Two things -

1. I like the idea of the constatine like prisons. That is what I was going to suggest.
2. I love/adore Jeanie's umbrella idea. Ever since I first read of it (months ago), I've used that at dusk and night when worried about owls.

have any other neighbors had any problems with the dogs or the people?

Maybe when reporting to ac you won't have to give name, if the dog can jump into your yard I would think he would jump into the street. just a thought

do the people own or rent? If they rent the landlord would not be happy with the liability either

This is what I was thinking!

Ugh how scary!

You could try a hot wire but it did not work for my Aussie/ pointer. He was an escape artist. He would climb chain link and jump over when touching the wire would yelp and keep going. Our fence is now 8 ft tall originally 6ft when we first moved in. He couldn't get out of that plus we had to line the fence with cinder blocks to keep him from digging out. Ten years later now he hasn't escaped since.

We lived in suburban country so did not share fence.

We have stray dogs in our neighborhood at times. Our yard is totally fenced in with chain link, but we were afraid dogs might clear our fence so we had three rows of barbed wire (each level going outward) added to the top of the fence. That was 14 yrs. ago and a dog has yet to clear the fence. I also am out with the girls every time they are out.

Better check your city code before you consider installing a hot wire. They are illegal in many places and your neighbor might report you. My neighbor ran one unbeknownst to me along our fence to keep his dogs off it and my little 5 year old niece climbed up on the fencing into the 3rd row of cox fencing - about 8" up, wearing open sandals to look at the dogs before my sister could get to her, felt a shock on the skin of her foot, got scared and screamed like a Banshee, lost her hold and fell, ripping open her chin on the fencing, bit through her tongue as she fell, bled and bled and screamed and screamed and once we got her back from the ER and cleaning and stitches and tetanus and antibiotics and pain medicine, me, my sister and BIL went OFF on that man, called the police and it was the awfullest mess. I think if the long cut had been on her cheek or got her eye instead of her chin and tongue bite, they would have sued him they were so horrified and scared and worried. She probably still has that scar on her chin. The police ticketed him and got an order from a judge for him to remove it. They came and watched while he did! I think he forever held it against me but I was not sure he'd rigged it right and was scared our son, who was only 1 at the time, would get hurt by it, too.

How tall is the fence? I didn't see the ht? Not already 6ft?

Thank you all for the suggestions going to call the city hall Monday and check on fence ordinances. No it is a standard height not 6ft.

Call animal control and I would make sure when you take them out to take something to spray in the dogs eyes, some kind of stick or a tazer. I know this sounds probably really crazy but I think I would do it if I had the problem I would put razor wire on the fence. You should not have to be afraid in your own yard. If he does it again I would take picture also and maybe even a video. People who let dogs out who are dog aggressive must not care if there dog gets into fights and killed.

Well sense you have to go out there any way with them they wouldnt be out there alone so I doubt they could do anything to your dogs. Also what if there dog attacks some in your neighborhood or there dog and you could have made a difference by complaining?

Did you ask them about taking care if the fence problem? Raising it on there side? It's their responsibility; they should be paying for it and fixing it, not you. Maybe they'd be willing to work with you without needing to report it.

I agree, a friendly chat first with your neighbours is the way forward. Keep it calm and ask if they mind a taller fence going up and the possibility of sharing the cost. Explain that you are aware their dog can come into your yard and as you have little ones your concerned they may get hurt. If they care about their dog they surely wouldn't want to run the risk of getting their dog taken away for being aggressive etc. as it is their dog doing the jumping over they should be responsible for doing the fence.
In order to keep things friendly and for you not to worry about any comeback you may have to compromise (although you shouldn't have to) and pay for it yourself but if it gives you peace of mind and keeps things "nice" with the neighbours it may be the way forward. Hope you get it sorted x

Im sorry that happened. Our chain link fence is pretty high because we have a barrier wall then the fence so we dont have that happen
